Feature 602 Linked Data: Relationships and Data Models can no longer be run #39

Open bobeal opened 2 weeks ago

bobeal commented 2 weeks ago

I was trying to run the feature 602.ngsild.RelationshipsAndDataModels but @jason-fox recently removed all the services from this tutorial (https://github.com/FIWARE/tutorials.Relationships-Linked-Data/commit/9163a7bf5b6304716a1cad0c8d62dc89ccc07a99) so the feature can no longer be run.

Are there plans to migrate it or will it be dropped?

As stated on the README:

To run this tutorial for NGSI-v2 developers, use the NGSI-v2 branch.

git clone https://github.com/FIWARE/tutorials.Relationships-Linked-Data.git
cd tutorials.Relationships-Linked-Data
git checkout NGSI-v2

./services create
./services start

The NGSI-LD tutorials have always only been available on the ngsi-ld branch. Whereas previously the NGSI-v2 were available on both master and ngsi-v2 (since there were a lot more of them than LD) - this was giving the false impression that v2 was the default. The current set-up places v2 and LD on an equal footing and explains the proper use-case for each variant.

Running ./services start on master now gives an informational message only.

The reasoning behind this is that I've seen users checking out a tutorial to learn NGSI-LD, forgetting to switch to the correct branch and then the tutorial text doesn't line up with the commands.

Agree with the equal footing but since there is no longer a ngsi-ld branch in the repository of the tutorial (only a ngsiv2 one)...

That tutorial is Smart Supermarket which is ngsi-v2 - or rather to quote from the master README:

To run this NGSI-LD tutorial for NGSI-v2 developers, use the NGSI-v2 branch.

It wa an early attempt to discuss the necessary minimal changes to switch a v2 system to run as LD and deliberately minimizes the role of @context - the proper ngsi-ld Smart Farm tutorials are instead user-context driven, which is the right way to design an LD system.
